The activities of beneficial soil microbes are crucial for the sustainability of any soil and plant growth. Humic acid stimulates microbial activity by providing the indigenous microbes with a carbon source for food, thus encouraging their growth and activity. Soil microbes are responsible for solubilizing vital nutrients such as phosphorus that can then be absorbed […]
As mentioned above, one way plant growth is improved is through the structural improvement of both clay and sandy soil allowing for better root growth development. Plant growth is also improved by the ability of the plant to uptake and receive more nutrients. Humic acid is especially beneficial in freeing up nutrients in the soil […]
When applied to clay soils, humic acid can help break up compacted soils, allowing for enhanced water penetration and better root zone growth and development. When applied to sandy soils, humic acid adds essential organic material necessary for water retention thus improving root growth and enhancing the sandy soil’s ability to retain and not leach […]
Humic acid. Humic acids are a principal component of humic substances, which are the major organic constituents of soil (humus), peat and coal. It is also a major organic constituent of many upland streams, dystrophic lakes, and ocean water. It is produced by biodegradation of dead organic matter.
In the soil, humic and fulvic acids are important chelators, combining minerals into organic compounds that are more available to plants. … They are often applied with microbial inoculants and liquid organic fertilizers. The quality of humic acid products varies widely.
